NGC 151 is a spiral galaxy in Cetus, 188 million light-years away
NGC 151 is a spiral galaxy in the constellation Cetus , 188 million light-years away. It shines at magnitude 11.6 and spans 3.7′ × 2.3′ of sky, about 204,400 light-years across. It is a telescope object, 6 inches or larger, and it is highest in the evening sky in November.
Galaxy: a system of billions of stars, gas and dust held together by gravity, far outside the Milky Way. Spiral galaxies have a disk with arms; elliptical galaxies are smooth, round or oval swarms of older stars.
